TYPEWRITING MACHINE.

Application led October 31, 1925. Serial No. 66,000.

f it has been found necessary, in order to produce a readilyportable machine, to either make provision for collapsing the carriage or type action of the machine for transportation, or to make the various operating parts of undesirably small size and mount the same in a short from front to height, or to resort to both expedients.. It is recognized that machines so constructed have disadvantages.

The principal object of the present invention is to.provide a readily portable, fourbank, singlefshift typewriting machine suitable for use inthe oliice or home and by travelers, having operating parts, including its type action, platen, line-spacing lever and ribbon mechanism, of rugged but light construction and of sizes usual in office machines.

A further object of the present invention is to provide a low or flat main frame corresponding in transverse and fore-and-aft dimensions with the frames of standard office typewriting machines and upon which the various operating parts are supported, either directly or by means of a small number of kspecially.formedsheet metal brackets, in such ma'nner that said `parts may be of the sizes usual in standard office machines.

A further object is to condense the typesbar mounting by placing the pivot segment of the type bars in a transverse plane inclined rearward at an angle of from the vertical, and mountingl it closer to the base of the frame of y the machine than is usual by securing the segment to the front face of an integral transverse partition wall of said frame, the partition wall being provided with front and rear parallel flat faces lying in planes inclined rearward at an angle of 30D from the vertical.

A further object is to pivotally mount the key levers on a horizontal fulcrum rod eX- tending transversely of the machine parallel with and close to the top edge of the transverse partition wall at a relatively high level in the main frame, the fulcrum rod being supported in a sheet metal plate secured to the rear face of the transverse partition wall by suitable screws, and the major portion of the segment lying below the horizontal plane of the fulcr um rod.

A further object is to provide the key levers with upwardly turned rear ends extending to the fulcrum rod, parallel to the rear face.

of the transverse partition walkthat is at an angle of 30 from the vertical, the main.

bank being substantially at the leve-l of the highest part of the main frame and the lowest bank above the level of the lowest part of the segment and the type-bar pivot wire.

A further object is to provide a corresponding plurality of intermediate or sub-levers,

preferably of bell-crank shape, pivotally' mounted in a slotted segment located in a horizontal plane, the arrangement being such that the forward arms of the sub-levers fan out in a substantially horizontal plane .and are adapted to be connected to the key levers of the different banks at different distances from the common fulcrum of the key levers, while 'the rear arms extend upwardly and rearwardly in vertical planes converging toward the rear of the machine.

Afurther object is to provide a. type-bar rest curved in an arc of Greater radius than the type-bar pivot'wire about a center eccentric to the center of curvature of the type-bar pivot segment and wire and supported at a higher level than the segment in a plane inclined more to the rear than the plane of the
